How to get a point on curve from a list of curves, each with a different point value?

Hello every one,

I have a series of non-uniform curves, what I want is to get a point on each curve where each point has a different location, for example:

- Curve (1) has a "Point on curve" value of "0.1"

- Curve (2) has a "Point on curve" value of "0.2"

..etc

Thank You..
